Definitions

  • the invention relates to the field of medical devices.
  • the invention concerns in particular a device for facilitating the insertion of an endovascular element over a guide-wire.
  • Cardiovascular diseases are the worldwide leading cause of mortality with more than 17 million deaths per year, thus more than 30% of the total mortality.
  • Ischemic coronary artery diseases represent the eighth cause of mortality in the world, and due to the continuous aging of the population, especially in the western countries, CAD related mortality continues to increase.
  • the main stem of all endovascular techniques is first to insert into the body, through the skin (e.g., through the groin or the wrist), a small catheter (i.e., long pre-shaped "plastic" tube). Once placed in the vessel, the catheter can be directed, under X-Ray guidance, everywhere in the vascular system in order to reach the target organ (e.g., heart, brain, kidney, etc.) and start the endovascular treatment.
  • a small catheter i.e., long pre-shaped "plastic" tube.
  • a contrast dye is injected through the catheter in order to correctly visualize the anatomy of the diseased vessel.
  • a small guide-wire is passed through the stenosis in order to reach the distal and healthy part of the vessel.
  • the operator i.e., interventional cardiologist, radiologist, vascular specialist, etc.
  • endovascular elements e.g., balloons, stents [metallic devices], etc.
  • Most of these elements have the same aim: to dilate the atherosclerotic narrowing and to allow a better blood circulation through the vessel, thus finally improving the organ function.
  • connection of all these endovascular elements over the guide-wire is a mandatory step in order to facilitate the navigation of the element (e.g.,balloon/stent) through the catheter and finally through the vessel's lesion.
  • element e.g.,balloon/stent
  • this step may be technically demanding, because:
  • the first goal of the invention is to provide a simple medical device in order to facilitate this repetitive manoeuvre (i.e., balloon/stent insertion over the wire performed several times every intervention).
  • the first goal of the invention is to provide a device that facilitates the insertion of an endovascular element over a guide-wire.
  • a second goal of the invention is to provide a device that will improve the manual ability of the operator by performing this endovascular element/guide-wire insertion operation, thus accelerating his manual skill in this particular manoeuvre, thus reducing the time of the intervention, finally improving the patient's and operator's comfort.
  • a third goal of the invention is to provide a device for facilitating the insertion of an endovascular element over a guide-wire that is easy to use and not expensive, in particular a device which use does not induce any cumbersome manipulation for being ready to perform the operation which is intended to perform. Furthermore, the device must be usable in a relatively dark/somber environment such as an operating room dealing with X-ray images.
  • a fourth goal of the invention is to provide a device which is adapted to be used independently from the flatness of area on which it is put.
  • it is intended to provide a device which is stable even when it is put on an uneven area such as a moving patient body.
  • a fith goal of the invention is to be built as smooth as possible in order to facilitate the glide of the endovascular element over the guide-wire.
  • the invention must be sufficiently rigid, in order to avoid deformation/kink/rupture when used during an endovascular intervention.
  • the shape of device is such that it renders said device able to provide a guiding support that facilitates manipulation of an endovascular element and a guide-wire in such a way that said endovascular element and said guide-wire slide towards each other along a common straight line.
  • the figures 1-3 show a device for facilitating insertion of a medical endovascular device over a guide-wire according to the preferred embodiment of the invention.
  • Figure 1 is a perspective view of the device according to the preferred embodiment of the invention.
  • the device comprises a first wall 101 and a second wall 102.
  • One edge of the first wall 101 is connected to one edge of the second wall 102.
  • the first wall 101 and the second wall 102 are both connected in such a way that an empty space 103 is present between the first wall 101 and the second wall 102.
  • the connection of the first wall 101 and the second wall 102 defines a straight axis 104.
  • the empty space 103 has a substantially prismatic shape and the angle ⁇ defined between the first wall 101 and the second wall 102 is equal to 90°.
  • theangle ⁇ is comprised between 30° and 120 ° .
  • the angle ⁇ is comprised between 80 and 100.
  • the device according to the preferred embodiment of the invention further comprises a third wall 105 and a fourth wall 106.
  • the third wall 105 and the fourth wall 106 are both connected by one of their edges to one edge of the first wall 101 and one edge of the second wall 102.
  • the device has a profile which has a shape of an "X" or a cross.
  • an empty space is present between the first wall 101 and the second wall 102, between the second wall 102 and the fourth wall 106, between the third wall 105 and the fourth wall 106 and between the third wall 105 and the first wall 101.
  • each one of the empty spaces identified above has a substantially prismatic shape.
  • the rest of the device may have any kind of shape.
  • the shape of the empty space 103 and/or the empty spaces identified above is curved.
  • the length L of the device is comprised between 2.5 cm and 30 cm and the weight of the device is comprised between 5g and 500g.
  • the device according to the invention is made in a material that is sterilizable.
  • the device according to the invention has a specific shape which is appropriate for drastically facilitating the insertion of an endovascular element over a guide-wire. Indeed, a process of inserting an endovascular element over a guide-wire precisely requires both elements to slide towards each other along a common straight and smooth line.
  • the shape of the device according to the invention is precisely such that the device provides an appropriate support for easily manipulating an endovascular element and a guide wire in such a way that they slide towards each other along a common straight and smooth line.
  • the shape of the device according to the preferred embodiment of the invention makes the device such that it can be easily used in a dark/somber environment such as an operating room dealing with X-Ray images. The operator only needs to drop the device on any surface and the device can immediately be used to perform the operation which is intended to perform.
  • the shape of the device in particular the X-shaped profile of the device, makes the device such that, once dropped on any surface, even an uneven surface such as a moving patient body, it remains sufficiently stable to be safely and efficaciously used.
